Which means I have now xenbr0 and vitbr0 interfaces running. As virbr0 just the new name for xenbr0? If so, can I just change that name in the older configuration files, so that all use the same interface name? -

...-i eth1), I can see only ingress(incoming) traffic of VM1. I am not able see outgoing traffic of VM1. If I create another bridge and trying same scenario with 2 VM then VM2 can see both ingress and outgress traffic. So want to know what is the issue? Is libvirt doing something different with this virtbr0 bridge? -- Sagar Dilip Shedge, Pune. With Regards.

I suspect it's a kernel issue. I mean, kernel takes several shortcuts in network stack when it comes to virtual NICs and virtual bridges. I've come across this when implementing QoS. I haven't tried your scenario out, I'm just guessing. BTW: depending on network type, li...
